Emission of CO2 into the atmosphere poses both morbidity and mortality health effect on human life. Studies have evaluated CO2 emissions from different sources in Nigeria, but levels of CO2 from residential area located within industrial layout have not been investigated. This was the gap which the study set out to bridge. The study was carried out at Oluyole Industrial Estate, Ibadan and a residential settlement within the layout. Levels of CO2, relative humidity and temperature were measured at 3 hourly intervals from 0600 to 2100 for a period of 7 consecutive days, at nine different points which included 5 industrial areas and 4 residential areas. These measurements were carried out with the aid of a calibrated portable CO2 Meter. The CO2 concentration of all the industrial and residential areas exceeded IPCC limit of 350ppm. Percentage spatial increases in CO2 emission in Res 1, 2, 3 and 4 compared to IPCC standard were 30.1%, 36.3%, 37.6% and 41.4% respectively. Res 4 had the highest on Monday among the residential areas. Res 4 had the highest CO2 level and differed significantly from the other residential areas. All the industrial and residential areas had temperature values higher than the recommended limit. Based on these findings, the study suggested that residential areas should be cited away from the industrial areas; and policies on maintaining environmental quality should be implemented and enforced.
